The XB-27 was proposed by Martin to fill an Army Air Corps requirement for a high altitude medium bomber. The Martin Model 182 was loosely based on the B-26 with design changes necessary for high altitude operation. The aircraft never progressed past the design phase of its development and no prototype aircraft were ever built.
